The X9460 is a low noise, low cost, high-end feature dual audio digitally controlled potentiometer. It integrates two digitally controlled potentiometers that can be used as stereo gain controls in audio applications. The position of the wiper on the array is controlled by the user through the 2-wire serial bus interface. The X9460 implements the digitally controlled potentiometer using 31 polysilicon resistors in a log array and connects tap points between each resistor to the wiper terminal through switches. It is designed to minimize wiper noise to avoid pops and clicks during audio volume transitions.
